03:58 AM veegee: I just checked my electricity bill
04:05 AM veegee: It's < $0.10/kWh
04:05 AM veegee: This is for commercial 600V three phase power
04:05 AM veegee: It's even cheaper than residential
04:05 AM veegee: I thought it would be more for some reason
04:06 AM veegee: Going to run 9 tons worth of AC cooling power
08:56 AM CaptHindsight[m]: @veegee the power to melt 18,000 pounds of ice in 24 hours? That doesn't sound very metric.
09:04 AM rs[m]: seems the matrix<->irc bridge ate some messages
09:04 AM CaptHindsight[m]: veegee: https://www.convert-me.com/en/convert/power/mrt.html?u=mrt&v=9
09:05 AM CaptHindsight[m]: rs: yeah, it's not 100%
09:05 AM * rs[m] uploaded an image: (80KiB) < https://libera.ems.host/_matrix/media/r0/download/inframax.eu/jQOEFTuJVasJFhpadzdaHTvv/image.png >
09:05 AM CaptHindsight[m]: works when it works
09:06 AM rs[m]: I didn't get veegee's messanges before Tom_L's "that's why they use it"
11:04 AM Roguish: JT[m], going Easy Rider today ????
11:18 AM roycroft: wonderful
11:18 AM roycroft: we have thunderstorms in the forecast for the mountain regions
11:18 AM roycroft: we already have more fires than we do at the beginning of august
11:18 AM roycroft: now there will be dozens of new fires
12:53 PM Tom_L: rs[m], sometimes there is quite a lag
02:41 PM Eric_ is now known as unterhausen
02:45 PM aaroncnc: so on a vfd the 0-10v signal is setup such that 10v is zero rpm and 0vish is max speed? for some reason this seems backwards to me but this is the first time i have put that signal on my scope
02:46 PM _methods: is jymm alright
02:46 PM _methods: all those fires going right thru his area aren't they?
03:01 PM DaViruz: aaroncnc: i've never seen it done that way
03:02 PM aaroncnc: thats what i was thinking.
03:02 PM aaroncnc: thought it would follow not inverse. but i am tinking around with new hardware so maybe a glitch i dont know.
03:06 PM CaptHindsight[m]: aaroncnc: are you using Remora?
03:06 PM aaroncnc: CaptHindsight[m], Yes i am
03:07 PM CaptHindsight[m]: been following the forum for that and a few similar projects
03:08 PM CaptHindsight[m]: I haven't tried using remora yet
03:08 PM CaptHindsight[m]: but am looking at porting to STM32
03:09 PM aaroncnc: This may not be a fault of remora tho. i am using another board to convert the pwm to a 0-10v signal
03:09 PM CaptHindsight[m]: so that it would be useful to me
03:10 PM CaptHindsight[m]: you can setup the VFD how you wish
03:11 PM CaptHindsight[m]: 0V can be top speed or stop, however you can program the VFD to respond
03:12 PM CaptHindsight[m]: some of the crappy BOB's don't go down to 0V
03:12 PM CaptHindsight[m]: but do reach 10V
03:12 PM aaroncnc: i know i can even program it to take a pwm but this machine is setup to be controlled with different setups. i am keeping the original ISA card controller inplace and trying to not reprogram the vfd
03:13 PM CaptHindsight[m]: so if the BOB only goes down to say 0.3V using that for max speed still works vs not letting the VFD slow down to 0 rpm
03:14 PM CaptHindsight[m]: which VFD are you using?
03:16 PM aaroncnc: i dont remember right now. i had looked it up in the past
03:16 PM CaptHindsight[m]: just curious
03:20 PM aaroncnc: LENZE 8200
03:20 PM aaroncnc: i think
03:20 PM CaptHindsight[m]: jymm if you're not dead please let us know, if you are then ignore this message (jymm appreciates dry humor, if you are offended then please don't read this or I'll send out comfort rays the best I can)
03:23 PM serp: Do you suspect ill of jymm
03:24 PM CaptHindsight[m]: I suspect nothing
03:24 PM _methods: i don't know
03:24 PM _methods: i think he lives around where those lava fires are going on
03:26 PM CaptHindsight[m]: https://www.fireweatheravalanche.org/fire/
03:27 PM satiowadahc[m]: Wow this has really picked up since I last checked on it
03:27 PM CaptHindsight[m]: https://fsapps.nwcg.gov/
03:27 PM satiowadahc[m]: and its less on fire than the mailing lists /s
03:32 PM CaptHindsight[m]: the hiccup on the ML is just "stick-n-stones" vs "words cut deeper than swords", and already over
03:34 PM satiowadahc[m]: lol
03:43 PM JT-Shop: https://forum.linuxcnc.org/40-subroutines-and-ngcgui/42926-save-subroutine-file-and-location?start=0
03:44 PM JT-Shop: someone please tell me why I'm failing to communicate with this cat
03:46 PM CaptHindsight[m]: he seems new to Linux and directory structures
03:49 PM CaptHindsight[m]: he might be thinking that he is a "superuser" as he states
03:49 PM CaptHindsight[m]: since he's using sudo and also changing permissions to folders and files
03:50 PM CaptHindsight[m]: the first time I installed Linux I made myself root
03:51 PM CaptHindsight[m]: what can go wrong?
03:51 PM CaptHindsight[m]: and i like to own my mistakes
03:56 PM veegee: Nothing wrong with being root if you know exactly what you're doing
03:57 PM veegee: most people blindly `sudo` anyway
03:59 PM CaptHindsight[m]: LCNC doesn't run as root
03:59 PM CaptHindsight[m]: for more fun
04:05 PM veegee: Happy Canada Day captain_morgan
04:05 PM veegee: I meant CaptHindsight[m]
04:05 PM roycroft: people who routinely log in as root when they don't need to should be fired
04:05 PM roycroft: like my boss
04:05 PM roycroft: :)
04:06 PM roycroft: he's hosed so many things over the years
04:06 PM Tom_L: you know you love your boss
04:06 PM Tom_L: with all his conspiracy theories etc
04:06 PM roycroft: and if he were not root at the time he'd have hosed significantly fewer things
04:06 PM roycroft: yeah, and you haven't heard the latest one
04:07 PM roycroft: apparently hillary clinton was so mad about losing the 2016 election that she colluded with the chinese to release the covid-19 virus shortly before the 2020 election, hoping it would cause the president to lose
04:07 PM roycroft: and his proof of this?
04:07 PM roycroft: the president lost
04:08 PM roycroft: and there's "no other way he could have lost"
04:08 PM CaptHindsight[m]: damn, that is clever
04:09 PM roycroft: it's almost as clever as obama's parents flying to hawaii in 1961 to conspire to plant a fake birth certificate in the hospital so that he could be elected president 45 or so years later
04:10 PM CaptHindsight[m]: 1961 I see
04:10 PM CaptHindsight[m]: same year a certain president took office that was later assainated
04:10 PM roycroft: that's the year obama was born
04:11 PM roycroft: and they also planted fake birth announcements in the newspapers at the time
04:11 PM CaptHindsight[m]: 100 years after the civil war began
04:11 PM CaptHindsight[m]: exactly
04:11 PM CaptHindsight[m]: if you know history you can come up with all sorts of fun stuff
04:12 PM roycroft: conspiracy theories require a lot of imagination
04:12 PM CaptHindsight[m]: too bad they don't teach much of it anymore
04:12 PM roycroft: there are so many random dots
04:12 PM roycroft: it takes cleverness to connect a bunch of them and spin a good yarn about how they are related when they're really not
04:13 PM CaptHindsight[m]: just a creative writing class
04:14 PM Tom_L: roycroft, she's crazy enough that's almost believeable
04:14 PM roycroft: those classes are hard to pass unless you're a cute, flirtatious, blonde girl
04:15 PM CaptHindsight[m]: and the willing believers
04:15 PM roycroft: regardless of whether the professor is male or female
04:15 PM roycroft: because we know that all female english teachers are lesbians
04:15 PM veegee: I've never heard that one before ^
04:16 PM roycroft: well you don't speak english - you speak canadian
04:16 PM CaptHindsight[m]: i thought it was lesbians or feminists...
04:16 PM CaptHindsight[m]: and not just femisinsists
04:16 PM roycroft: happy we're skipping canada day this year day, btw
04:17 PM CaptHindsight[m]: feminists that hate men vs the ok with men being equal types
04:18 PM CaptHindsight[m]: well HR is difficult work
04:19 PM CaptHindsight[m]: if Hillary had not killed JFK, Lincoln and Jesus would she of made a better candidate? We will never know.
04:21 PM Tom_L: yeah she put monica in bills path so she'd have time to do all that too
04:22 PM veegee: Any recommendations on silver brazing filler?
04:22 PM Tom_L: hvac supply
04:23 PM roycroft: it depends on what you're doing
04:24 PM veegee: Brazing carbide to mild steel
04:24 PM veegee: 45% or 56% silter?
04:24 PM roycroft: jewler's suppliers have silver solder with various melt temps
04:24 PM Tom_L: https://www.amazon.com/Supplying-Demand-Brazing-Perfect-Refrigeration/dp/B07PRF82VX
04:24 PM veegee: Amazon has it
04:24 PM Tom_L: they sure do
04:24 PM roycroft: so if you have to do multiple soldering operations on a single part you can start with the high melt stuff and work your way down
04:25 PM roycroft: and the last time i brazed carbide to mild steel i used jeweler's silver solder
04:25 PM roycroft: the hvac stuff is probably cheaper though
04:26 PM Tom_L: https://carbideprocessors.com/pages/brazing-carbide/brazing-tungsten-carbide.html
04:26 PM roycroft: i used jeweler's silver solder because i had it in stock
04:26 PM veegee: "There are several brazing alloys used for carbide. The classic is BAG-3, 50% silver with Cadmium" Oh fun, cadmium
04:27 PM CaptHindsight[m]: do they have Amazon stores up in Canada?
04:27 PM veegee: Not that I know of
04:28 PM veegee: My welding supplier has it too. They have the 45% and 56%
04:28 PM veegee: and a whole bunch of flux coated rods
04:38 PM CaptHindsight[m]: veegee_: you making your own tooling?
04:39 PM CaptHindsight[m]: that reminds me to earn another PhD for working on micro EDM
04:39 PM veegee: Brazed carbide
04:39 PM veegee: yes
04:40 PM veegee: Carbide the way I want it
04:40 PM veegee: don't have to worry about stupid chipbreaker speed/feed requirements
04:41 PM CaptHindsight[m]: veegee: what is the situation up there for larger tanks of welding gas? Can you refill big tanks that YOU own or just rent and refill?
04:41 PM veegee: I rent the large tanks, cost is $100/year
04:41 PM veegee: There are places that fill your own tanks
04:42 PM veegee: Filling cost is almost the same for argon, so I get the biggest tank possible
04:42 PM veegee: There are also the newer high pressure tanks with built in regulator from praxair
04:42 PM CaptHindsight[m]: I drive up to WI to get my big tanks swapped
04:43 PM veegee: almost double the mass of stored gas and refilling price is almost the same
04:43 PM CaptHindsight[m]: near the big city they won't touch your big tanks unless you rent from them
04:43 PM veegee: Even if certified?
04:44 PM roycroft: when i switched gas shops they would charge me a recertification fee for any tanks i bought elsewhere
04:44 PM roycroft: i don't deal with places that only do rental tanks
04:44 PM roycroft: that's a scam
04:45 PM veegee: eh, not that bad
04:45 PM veegee: I like to extract the acetone out of the acetylene tanks after I'm done with the acetylene
04:45 PM veegee: there's a lot of acetone in there and acetone isn't cheap
04:46 PM CaptHindsight[m]: in WI they just check the dates on the bottle
04:46 PM CaptHindsight[m]: around here they won't touch it if it's big, certified and has a letter from your parents
04:47 PM CaptHindsight[m]: unless you rent
04:47 PM CaptHindsight[m]: my parents are dead so i just write for them posthumously
04:48 PM veegee: They are high pressure vessels, so I get it
04:48 PM veegee: also the rent price isn't horrible, so not much for me personally to complain about
04:48 PM veegee: $100/year is something I won't even notice on my credit card
04:49 PM veegee: I own a small cylinder which they will refill, but as the refill cost is nearly the same, I only use my big cylinders. Not worth using small cylinders unless you need the portability.
04:50 PM veegee: Refill cost easily eclipses rent cost if using small cylinders
04:51 PM veegee: https://www.youtube.com/watch?v=PCGBISlVKMM there we go, 45% silver and black flux is what I need
04:51 PM roycroft: i don't have mine refilled
04:51 PM roycroft: i just swap them out
04:51 PM roycroft: it's a lot faster
04:52 PM veegee: So you don't own the tank then?
04:52 PM roycroft: i hand them an empty; they hand me a full one; and i pay for the gas
04:52 PM roycroft: yes, i own it
04:52 PM roycroft: but i in effect trade it in every time
04:52 PM CaptHindsight[m]: i find the small tanks easier to move than the larger ones
04:52 PM veegee: Oh it's that kind of service
04:52 PM veegee: CaptHindsight[m] I have 5 forklifts :P
04:52 PM roycroft: some places around her won't fill a tank for a customer - they only do swaps
04:52 PM CaptHindsight[m]: but i only have one small tank and a bunch of big ones
04:53 PM roycroft: other places charge more if the customer wants their own tank refilled
04:53 PM roycroft: this is the reason that the shops around here charge a recertification fee if you bring them a bottle from another shop
04:53 PM roycroft: they also don't check the date when you swap one from their own shop
04:53 PM CaptHindsight[m]: bunch of O2, steel mix and nitrogen
04:53 PM roycroft: so if you bring them an expired bottle you get a valid one for no extra cost
04:54 PM roycroft: i have two small bottles
04:54 PM roycroft: from an old backpack oxy-acetylene torch
04:54 PM roycroft: i use the oxygen tank on my brew system to inject oxygen in the wort as it comes out of the kettle
04:54 PM roycroft: and the acetylene one i use for my acetylene-air jeweler's torch
04:54 PM roycroft: my other tanks are all big ones
04:55 PM veegee: I use my backpack kit to clear out bunkers
04:55 PM CaptHindsight[m]: thanks for reminding me to build a mosquito trap using propane
04:55 PM roycroft: oxy and acetylene for the big torch
04:55 PM roycroft: argon for the tig welder
04:55 PM roycroft: and co2-argon for the mig welder
04:55 PM veegee: damn, that explains why my welds never worked
04:56 PM veegee: had the oxygen hooked up to the tig welder and the argon hooked up to the torch
04:56 PM roycroft: and i have several smaller (5lb and 10lb) co2 tanks for beer
04:56 PM roycroft: that's pretty hard to do
04:56 PM roycroft: because the regulators have different threads
04:56 PM roycroft: for good reason
04:56 PM roycroft: it *should* be hard to do
04:56 PM veegee: Yeah I know, they make it pretty idiot proof
04:56 PM CaptHindsight[m]: I cut with O2 and propane
04:56 PM roycroft: yet you still managed to do it :)
04:57 PM veegee: oxy propane eats oxygen
04:57 PM veegee: 6:1 vs 2:1 for acetylene
04:57 PM CaptHindsight[m]: I get free propane tanks at the Menards
04:57 PM veegee: but yeah for cutting, doesn't matter
04:57 PM roycroft: the nearest menard's is over 1500 miles from here
04:58 PM Tom_L: roycroft, i wouldn't mind that personally
04:58 PM Tom_L: one of my kids worked there for a short stint and they treat their employees poorly
04:58 PM roycroft: yeah, i was never impressed with menard's
05:00 PM veegee: https://www.amazon.ca/Carbide-Indexable-Milling-CCMT09t304-CCMT32-5/dp/B075WTV4TZ
05:00 PM veegee: Look at the price of those inserts
05:00 PM veegee: I bought them and they actually work well
05:00 PM veegee: $15 / 10 inserts
05:00 PM veegee: positive rake
05:01 PM Tom_L: how does C5 compare to C6?
05:01 PM veegee: Very close, exactly what you expect
05:02 PM veegee: C5 slightly tougher, C6 harder but more brittle.
05:02 PM veegee: For interrupted cuts, I usually just stick with M2 HSS
05:02 PM veegee: Or C2 brazed carbide
05:02 PM CaptHindsight[m]: hah, the matrix bot is just catching up to 10 minutes of discussion
05:03 PM Tom_L: never been wild about that either, joined cause i was interested in qtpyvcp
05:03 PM veegee: at low temperatures, HSS is excellent
05:04 PM Tom_L: yeah but ya gotta use coolant
05:04 PM veegee: But low temperature is key. For 25mm round bar, I stick to < 400 RPM
05:04 PM veegee: Yeah I have to get some
05:04 PM Tom_L: i use rustlik
05:04 PM veegee: Mist coolant would work best
05:05 PM veegee: But need to make slide way covers before I use water based coolant
05:05 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Rustlick1.jpg
05:06 PM Tom_L: there are many good ones out there
05:06 PM roycroft: for carbide tooling, you really don't need any coolant for most operations
05:06 PM Tom_L: that was part of the discussion yes
05:06 PM roycroft: just don't ever dab coolant on carbide
05:07 PM roycroft: either do something continuous, mist or flood - it doesn't matter, or no coolant at all
05:07 PM roycroft: carbide can tolerate heat, but it cannot tolerate sudden thermal stresses
05:07 PM veegee: If I want to get tight tolerances, have to use coolant or the part expands
05:07 PM veegee: when the part swells, that also ruins the surface finish
05:07 PM roycroft: if you get it too hot
05:07 PM veegee: unless you have wiper inserts
05:07 PM roycroft: set your speeds and feeds properly and it won't get hot
05:07 PM veegee: I do, and it still gets hot
05:08 PM veegee: That's normal, can't avoid it
05:08 PM roycroft: you get perfect, light blue c-shaped chips every time?
05:08 PM veegee: Yes
05:08 PM roycroft: you're a better machinist than most
05:08 PM veegee: for low feeds, there's more cutting per unit length.
05:08 PM veegee: It's automatic feed, I'm not turning the wheel
05:09 PM veegee: all you need is a calculator, skill really isn't a factor
05:09 PM Tom_L: i've been adjusting all my tool feeds now that i have a decent spindle motor
05:10 PM Tom_L: i like the fswizzard app
05:21 PM veegee: Hmm, TIG welding M42 might also be an option, especially if the HSS is clamped to a copper heatsink
05:22 PM Tom_L: don't you want it to flow under the carbide?
05:22 PM veegee: I mean TIG welding a piece of HSS to mild steel
05:22 PM Tom_L: O
05:23 PM veegee: M42 and T15 HSS are expensive but have high red hardness
05:23 PM veegee: Making a mechanical holder would also work I guess
05:24 PM veegee: T15 is really nice. Excellent edge holding
07:23 PM _unreal_: so i have a heavy duty small scissor jack at work that one of the boats tossed out. I do not know if it will work or not I have not tested it yet
07:23 PM _unreal_: the lead screw is a tiny it rusted but I think I saved it in time
07:23 PM _unreal_: it currently has a DC 48v :( worm gear motor on it
07:24 PM _unreal_: not sure what the current rating is on it yet. I just have not had the time to even look at the damn thing
07:24 PM _unreal_: I'm toying with a few options
07:24 PM _unreal_: one is switching it to a stepper motor BUT
07:24 PM _unreal_: I would have to rebuild the worm drive setup
07:27 PM _unreal_: and looks like I did get rid of my gear reduction steppers :/
07:27 PM _unreal_: shit
07:28 PM _unreal_: so I'm toying what what I might do thoughts
07:28 PM _unreal_: I'd like to set the thing up with an arduino or something
07:29 PM _unreal_: and a simple POT to set the height
07:29 PM _unreal_: it has two limit switches already built in
07:33 PM roycroft: i finally broke down and bought a router circle jig - i have several holes to route of different sizes, and the old method of drilling holes in a stick would just be to tedious
07:33 PM roycroft: the one i got claims to be dead nuts accurate, and had a granularity of 1/16" diameter, which is fine
07:34 PM roycroft: and i can swap the 1/4" router bit for a 5/16" bit and get a 1/32" offset if i need finer granularity than 1/16"
07:35 PM roycroft: i could even use a 7/32" bit to get 1/64" granularity
07:38 PM veegee: army rangers, navy seals, no idea how these guys pass the training
07:38 PM veegee: well, genetics is how
07:39 PM _unreal_: hum
07:39 PM veegee: but I can't imagine having that much physical strength and endurance
07:39 PM _unreal_: heh
07:39 PM _unreal_: I use to be a big fitness buff in my 20's
07:40 PM _unreal_: I was a big boyaaaaaa
07:40 PM veegee: Best I can do is a few pull ups and a burst of upper body strength, but very little endurance
07:40 PM _unreal_: heh
07:40 PM _unreal_: lard ass
07:40 PM veegee: I'm not fat
07:40 PM _unreal_: low fat lard ass
07:40 PM _unreal_: LOL
07:40 PM veegee: I'm 5'10", 170 lbs
07:41 PM _unreal_: so about my size
07:41 PM veegee: I thought you said you were big
07:41 PM veegee: That's average
07:41 PM _unreal_: I use to bench 170
07:42 PM _unreal_: I'd do 80 dumb bells over/behind myhead
07:42 PM _unreal_: NOT easy
07:42 PM veegee: yeah that's difficult for sure
07:42 PM _unreal_: My friend who dwarfed me would do 100's
07:42 PM _unreal_: always begging me to spot him
07:42 PM _unreal_: back them
07:42 PM _unreal_: then
07:43 PM veegee: I don't do anything that requires someone to spot
07:43 PM veegee: Inherently dangerous for both people
07:43 PM _unreal_: naa
07:44 PM _unreal_: though now I always hav people saying what cha puffen your chest out for.... I'm like M/F'er I have not lifted in near 20 years
07:45 PM veegee: I have to get back to it. I stopped 4 years ago after my shoulder injury
07:46 PM veegee: Long story, but motorcycle accident in the middle of nowhere. Ball joint of the left shoulder exploded inside the joint
07:46 PM veegee: First surgery made it worse because they didn't know what the injury was
07:46 PM veegee: There's chronic pain. I can deal with it most of the time. Pain isn't proportional to applied force
07:47 PM veegee: It's just always there no matter what. And for some reason no one can explain, worse when it rains
07:47 PM veegee: Range of motion is 90% of original miraculously
07:48 PM veegee: But all the muscles related to moving that shoulder are weaker than on the right side
07:49 PM veegee: Advil makes the pain mostly go away, so we know it's inflammation. But can't take NSAIDs every day
07:57 PM _unreal_: nope
07:58 PM _unreal_: veegee, look into holistic health methods for helping that kind of an issue and ways to pad the symptoms
08:26 PM veegee: https://www.neutrik.com/en/neutrik/products/powercon/powercon-20-a
08:26 PM veegee: I don't understand what "power in" vs "power out" means
08:27 PM veegee: so use the blue plug/socket on the tool side, and the gray plug socket on the power supply panel side?
08:29 PM CloudEvil: yes
08:33 PM CloudEvil: Err, no
08:33 PM CloudEvil: You can't interplug the blue and gray
08:33 PM veegee: Yeah, so blue plug and blue socket on the tool side
08:33 PM veegee: gray plug and gray socket on the wall side
08:34 PM CloudEvil: That's one option
08:34 PM CloudEvil: There is no particular reason not to use all blue or all gray if you don't care about interplugging
08:34 PM veegee: Yeah that's what I was thinking
08:35 PM CloudEvil: For example, if you were connecting a generator to a cabinet and thence to loads
08:35 PM CloudEvil: then blue/gray would stop fuckups
08:37 PM veegee: Now to find a decent connector for my 600V equipment
08:38 PM veegee: I'm tempted to use NEMA L15-30 for everything, but that's obviously dangerous
08:38 PM veegee: Cheap and easily available though
08:45 PM veegee: If I were to use one colour for everything, what's the worst that could happen? Blue socket on the tool, blue socket on the wall side. Cable with blue plugs on both ends
08:46 PM veegee: Even if I use it for my light towers for daisy chaining, can't really connect it in any way that would cause harm because the blue would connect to the same power line anyway
08:47 PM CloudEvil: You get teh cable the wrong way round
08:47 PM veegee: CloudEvil how would that work?
08:47 PM veegee: Blue plug has 3 pins: ground, line, neutral
08:47 PM CloudEvil: It doesn't actually matter.
08:47 PM veegee: they should always correspond to ground, line, neutral no matter what
08:48 PM veegee: so not like it would be possible to ever short circuit line and neutral
08:48 PM CloudEvil: It matters in a damaging way if you're using them for (for exmple) 110/220 or
08:48 PM CloudEvil: AC/DC
08:48 PM veegee: oh
08:48 PM veegee: so for single phase AC, single voltage everywhere, can't go wrong
08:48 PM CloudEvil: Pretty much, unless you're doing stuff like safety interlocks with it
08:48 PM veegee: I'm just going to designate them for single phase 240V
08:49 PM veegee: nothing complicated. Just hand held power tools, daisy chaining lamp posts, etc.
09:25 PM enleth: veegee: powercon true1 is a better option than 20 A, it's outdoor rated and breaks safely under load
09:25 PM enleth: I'm using it for power tools
10:34 PM veegee: enleth I would get it, but I can't find it on aliexpress for < $1/piece
10:34 PM veegee: I need like 30 plugs and sockets
10:35 PM perry_j1987: mmmm harmonic 4th axis with tombstone setup would sure be nice to make parts on
10:42 PM Tom_L: yup
10:58 PM veegee: I just realized my mistake of cutting the recess part of the chuck back plate too small may be an advantage
10:59 PM veegee: Now I can use set screws to adjust the chuck on its back plate to get zero runout
10:59 PM veegee: so pretty much like a bison set tru system
11:36 PM veegee: Every bloke should drill 4 holes between his chuck and back plate for fine adjustment!!
11:36 PM veegee: Don't need to pay the Bison tax for that
